BLIND OPERATOR AND LOCK.

Specification of Letters Patent,

Patented Oct. 17, 1905.

Application filed June 10, 1903. Serial No. 160,789.

1'0 (1Z5 who/w it 72-May concern/.-

Be it known that I, KARL OTTO HUTT, a citizen of the United States, residing in Malden, in the county of Middlesex and State of provide a simple and highly-efficient mechanism for the pul ose specified.

The particular eatures of this invention will be pointed out in the claim at the end of this specification.

Figure 1 is an elevation showing the blinds in their closed position and looking from the outside of the house; Fig. 2, an elevation with the blinds closed and looking from within the room; Fig. 3, a detail in elevation and section, on an enlarged scale, of the operating mechanism to be referred to; and Figs. 4 and 5, details to be referred-to.

Referring to Fig. 3, a represents a rod or arm which is engaged with the blind b, and, as shown, the said rod is extended through a staple 0, attached to the under side of the blind. The rod a is secured to the end of an,

upright shaft (1, extended through the window-sill e and rovided below the same with a bevel-gear f, avin a hub g, which-rests on a washer or collar fast on a bent stud,

'post, or bracket 11, attached to a plate 7,

which is screwed or otherwise fastened to the outside of the building k. The supporting bracket or post 'i is rovided with an annular groove m, into which projects a screw n, carried by the hub of the gear f, whereby the bevel-gear is locked on the support 'i against longitudinal movement, yet is free to rotate thereon. The bracket or 0st 11 is rovided with a laterally-extended. ug or ho low boss 7, which forms a bearing for a shaft 8, extended through the base of the window substantially at right angles to the shaft d. The shaft 8 has secured on it, as by a screw 9, a bevel-gear 10, which meshes with and rotates the beveled ear f The shaft 8 within the house or buiTding has a bearin in a rosette 12, screwed or otherwise suitaby secured to the building. The shaft 8 is extended through and beyond the said rosette and is provided with a portion 13, which is angular in crosssection and upon which is fitted the hub 14 of a handle 15, having at its front end a recess or socket 16, in which is located a helical spring 17, which bears against the hub 14, and a nut or disk 18, which engages the threaded end 19 of said shaft. The hub 14 of the handle 15 is capable of movement longitudinally on the shaft, but is fitted onto the angular portion 13, so as to cause the shaft to be rotated when. the handle is turned, Provision is made for locking the handle from rotation under normal conditions, and for this purpose the rosette 12 is provided with one or more teeth or projections 20, which cooperate with suitable recesses or notches 21 on the front face of the hub 14. (See Figs. 4- and 5.) In the present instance the rosette is shown as provided with two teeth 20, which are arranged substantially diametrically opposite, and the hub 14 is shown as provided with three sets or pairs of notches 21, similarly arranged.

Under normal conditions the notches 2-1 engage the projections 20, as represented in Fi 3, and when in this position the shaft 8 is lofied against rotation and the blind is held stationary, which may be in its closed or fully-opened position or in a partially-opened position. As shown in Figs. 1 and 2, the

linds are closed. Assume that it is desired to open the same. In this case the operator within the room pulls upon the handle 15 until the recesses or notches 21 are disengaged from the teeth or projections 20, after WhICh the handle is turned in the proper direction to open the blind, which is accomplished by the evelgear 1O rotatin the bevel-gear f and its shaft (1, the latter in its rotation carrying with it the crank or rod (1, which is in engagement with the blind by the staple c. When the blind has been opened to the extent desired, the 0 erator releases the handle, which is moved y the spring 17, so as to again engage a pair of the notches 21 with the teeth or projections 20, and thus lock the blind in the position into which it has been turned. The outward movement of the handle 15 may be limited, as herein shown, by a shoulder 25 on the interior thereof engaging the nut or disk 18.

Provision is made for enabling the blind to be removed when desired, and for this urpose the crank rod or arm a is detachably astened to the shaft d, which may be ac- IIC Correction in Letters Patent No. 802,167.

com whic end of the crank or arm after the latter has been passed through a hole in the shaft (1, as clearly shown in Fig. 3, the crank or arm a having on it a collar or projection 27, which engages the shaft (1 on the side opposite to the in.

Tl ie mechanism on the outside of the house or building may be protected from the weather by a suitable cover 30, which ma r be screwed or otherwise secured to the build 111.

By the term blind I desire to be understood as including a shutter.

I claim The combination with a blind, of a crank arm or rod in engagement therewith, a vertically-arranged shaft to which said crank arm or rod is secured, a bevel-gear fast on said shaft and provided with a hub, a bracket attached to the building and u on the upper end of which said hub is oosely fitted,
